Esophageal manometry in 28 systemic sclerosis Brazilian patients: findings and correlations.

Systemic sclerosis (SSc) is a multisystem disease of unknown etiology. Esophageal involvement affects 50-90% of patients and is characterized by abnormal motility and hypotonic lower esophageal sphincter. Data on the association of esophageal abnormalities and age, gender, SSc subset or duration, autoantibody profile, esophageal symptoms, and medication are lacking or conflicting. The aim of this study was the evaluation of these associations in Brazilian sclerodermic patients from the Rheumatology Division, Clinics Hospital, Federal University, Minas Gerais. They underwent medical records review, clinical interview, and esophageal manometry. The normal cutoff level for lower esophageal sphincter pressure was 14 mmHg. Abnormal peristalsis occurred when less than 80% of peristaltic waves were propagated. P-values less than 0.05 were considered significant. Twenty-eight patients were included: 71% were women. The population presented medium age and disease duration of 46 years and 12 years, respectively. Cutaneous diffuse SSc occurred in 39% and its limited form in 61%. Dysphagia, pyrosis, and regurgitation occurred, respectively, in 71%, 43%, and 61% of patients. Lower esophageal sphincter pressure and number of peristaltic waves-propagated medias were, respectively, 17.2 mmHg and 2.3. SSc-related manometric abnormalities were present in 86% of patients. Manometry revealed distal esophageal body hypomotility, hypotonic lower esophageal sphincter, or both, respectively, in 82%, 39%, and 36% of patients. One patient presented the manometric pattern of esophageal achalasia. Male patients more frequently presented hypotonic inferior esophageal sphincter. Manometric findings have had no relationship with the other variables. Nifedipine use did not influence manometric findings.

New once-daily, highly effective rescue triple therapy after multiple Helicobacter pylori treatment failures: a pilot study.

BACKGROUND: Helicobacter pylori treatment failure is a growing problem in daily practice. AIM: To determine the efficacy of the combination of rabeprazole, levofloxacin and furazolidone as a rescue therapy. METHODS: Duodenal ulcer patients previously submitted, without success, to at least two H. pylori treatment regimens were included. Gastroscopy (urease test, histological examination and culture) and (13)C-urea breath test were performed. All patients received a combination of rabeprazole 20 mg, levofloxacin 500 mg and furazolidone 200 mg (two tablets) administered in a single dose in the morning for 10 days. Clinical examination and a new (13)C-urea breath test were performed 90 days after therapy. RESULTS: Twelve patients (eight females and four males), mean age 43 (30-58) years were included. Two patients failed to complete the treatment because of nausea and vomiting. Ten patients completed the study and took all the medications as advised. Culture was obtained in six patients: 100 and 83% of the samples were sensitive to furazolidone and levofloxacin, respectively. Per-protocol and intention-to-treat eradication rates were 100 and 83% (P = 0.019). CONCLUSIONS: the combination of rabeprazole, levofloxacin and furazolidone in a single daily dose for 10 days constitutes a highly-effective and low-cost alternative as a third-line therapy in patients infected with H. pylori.
